from Mike from the Norton Authorized Support Team in his post here;
that removal in Vista is the same as removal in XP.
Details my differ, but the general procedure will be the same.
I have a backdoor.irc.bot in quarantine under Norton 360. I would like to remove it from my computer but previous posts on here only have instructions to remove this from Windows XP/2000. Can someone please tell me how to remove this tricky little guy?
